Security Incidents

Crypto platforms — and investors — have long suffered from hacker attacks and exploits. Now, artificial intelligence (AI) is making that threat even worse. That’s the view of Charles Guillemet, chief technology officer at crypto wallet provider Ledger, who said the economics of cybersecurity are

On April 1, the Drift Protocol on the Solana chain was attacked by hackers, resulting in losses of about $285 million and a sharp drop in TVL. The investigation found that the attackers carried out a social engineering infiltration lasting 6 months, using Durable Nonce to bypass multiple signatures, highlighting the threat that nation-state hackers pose to DeFi and raising questions about Circle’s response speed.

A six-month intelligence operation preceded the $270 million exploit of Drift Protocol and was carried out by a North Korean state-affiliated group, according to a detailed incident update published by the team earlier on Sunday. The attackers first made contact around fall 2025 at a major crypto c

A court in Qinzhou District, Tianshui City, Gansu Province, is trying a virtual-currency money-laundering case.

The court sentenced him to two years and four months in prison and fined him. The judge reminded the public to stay alert to related activities in order to prevent them from fueling crime.

Security incidents increased in the fourth quarter of 2025 and the first quarter of 2026, and the occurrence of code vulnerability exploits is linked to the rise of artificial intelligence.

On-chain investigator ZachXBT published a report stating that since 2022, Circle has repeatedly failed to properly carry out compliance in multiple incidents involving illegal funds, with amounts totaling more than $420 million. The report notes that in several security incidents, Circle did not freeze suspicious accounts in a timely manner, leading to severe losses. Despite having relevant mechanisms, Circle responded slowly when facing attacks and investigations into money laundering, which affected industry security.

The Japan Financial Services Agency has issued “Policy Guidelines for Strengthening Cybersecurity for Crypto Asset Exchange Businesses and Related Entities,” with the aim of strengthening investor asset protection. It proposes a three-layer security framework to address the new landscape of cyberattacks. In subsequent plans, it will conduct penetration testing on major operators and revise the guidance to raise security standards.

DeFi lending protocol HypurrFi issues a security warning, saying that its website domain has been compromised. It urges users not to use that domain and to pause interactions. The team confirms users’ funds are safe and is investigating the domain hijacking incident.

X is implementing a new feature that auto-locks accounts with their first crypto post to combat phishing attacks. This aims to reduce the misuse of hijacked accounts for scams while enhancing user security.

Onchain detective ZachXBT claims that Circle, the issuer of the USDC (USDC) stablecoin, has failed to freeze or blacklist about $420 million in illicit fund flows since 2022. Circle can freeze illicit funds and blacklist wallet addresses, but either took “minimal” action to freeze illicit flows or

The U.S. stablecoin company Circle has been accused of failing to effectively freeze more than $420 million in suspicious USDC funds. Investigators ZachXBT pointed out that since 2022, Circle has delayed freeze actions in multiple hack incidents, sparking questions about its compliance. The Drift Protocol attack involved in the incident has also made Circle’s criticism the focus. Market calls for Circle to raise its risk management standards were followed by serious losses to users caused by its delayed compliance enforcement.

Social media platform X will auto-lock accounts that mention cryptocurrency for the first time, requiring additional verification to deter crypto phishing scams. This new measure aims to eliminate incentives for attacks that hijack accounts to promote fraudulent tokens.

four.meme announcement: Because the project tax fee receiving address that starts with 0x9f4 has a defect, sell transactions have failed.

A product that combines cryptocurrency, adult content, and a high-risk lending mechanism has recently sparked heated discussion in crypto circles and on social platforms. The project, named “Hero Loan,” promotes the slogan “unsecured loans,” but requires users to upload private videos as a condition, and ties default risk to an adult-platform monetization mechanism—prompting many netizens to describe it as “an encrypted version of loan-sharking/porn lending.” The project even uses “If you think this won’t get used, it just means you haven’t reached rock bottom yet” as its promotional tagline, clearly targeting users with high risk and extreme capital pressure. However, shortly after it was exposed, one netizen said they had sent a video but didn’t receive any money; a KOL also responded that the project appears to have rug-pulled. But honestly, a private video is only worth 60 bucks—that’s just too brutal. “Hero Loan” targets people with nowhere left to go According to information on the official website, the product runs on BNB Chain and is positioned for “people who have nowhere left to go—

On-chain investigator ZachXBT accuses stablecoin issuer Circle of making more than $420 million in compliance execution mistakes since 2022, failing to promptly freeze the USDC funds involved, which led to funds draining in multiple security incidents, with a slower response time than competitors.
